not true, you can change a CPU without changing the motherboard assuming that the motherboard is compatible. Most motherboards are compatible, even laptops, across 2-4 different processors IE: my motherboard supports intel core i3,i5, i7, and intel pentium processors. BUT!!! i do warn, changing a CPU will void the warranty (should you have one, i assume you do), so do it at your own risk, and only have a trained technician do it. if you look up the specs for the motherboard inside your laptop, assuming you can find the information, it'll say what it's compatible with. sometimes you can look up the model of your laptop and it'll tell ya in the laptop specs.
